Application led September '20, 1911. Serial No. 650,372.

To all whom t may concern:

Be it known that l, @TTG CZARAN, al subjectof the King of Hungary, and resident of the city of New York, in the county of Queens and State of New York, have invented certain new and useful improvements in Motor-Flows, of which the following is a specification.

The present invention relates to an agricultural implement, and more particularly to motor propelled plows.

One of the objects of the invention is to provide such plows with a simple and highly eficient mechanism for propelling the same.

Another object of the invention is to produce a simple mechanism, whereby the turning plow or plows mounted upon the frame of the implement may be adjusted to drawv the same into or out of operation, or to accommodate for inequalities in the ground over which the implement passes.

A further object of the invention is to provide a mechanism to permit the positions of the plows to be readily adjusted so as to regulate the depth of the cut.

A still further object of the invention is to provide a plow with rotatable colters have ing radial digging or cutting blades, and

- with means for imparting a positive drive to said colters.

lVith these `and other objects in view,

which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangementand construction of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the siZeand pro! portion of the several parts and minor details of construction withoutdeparting from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side kelevation of a cultivator embodying the invention; Fig. 2 is a plan view of the same; Fig. 3 is a side elevation of one .of the rotary colters; Fig. 4 is a front elevation of the colter shown in Fig. 3; Fig. 5 is a front elevation, partly in section, of the means for drawing the plows into or out of operation; Fig. 6 is a side elevation of the same; Fig. is an lenlarged detail of the means shown in Fig. 5; Fig. 8 is av section taken on line 8-8 of Fig. 7; Fig. 9 is a side elevation'of ay detail of construction; Fig. 10 is a front elevation ofthe detail shown in Fig. 9; Fig. 11 is a front elevation of the means for attaching the plow beams to the frame of the implement; and Fig. 12 isa plan view of the detail shown in Fig. l1.

Fig. 13 is a front elevationof an enlarged detail of Fig. 7; and Fig. 14 is a similar view of the same detail showing the parts in other positions.

In the drawings, the numeral 20 designates the frame of the implement, which is,

preferably, rectangular in form, and supported at its front portion by an axle 21,r upon which the traction wheels 22, 22 are mounted. At its .rear end the frame is carried by a steering wheel 23, supported in a bifurcated standard 24, the upper end of which is rotatablyJ arranged' in a bearing 25, which latter is provided upon the frame 20. The operators seat is indicated by the numeral 26, and in front of this seat is arranged a steering wheel 27, the post 28 of which is provided at its lower end with a bevel gear 29, meshing with a similar gear 30, which is carried by ashaft 31. Upon this shaft is cut a worm '32, in engagement with a worm gear segment 33, which is rigidly secured in any suitable manner to the standard 24. By means of this arrangement the steering wheel can be given' a turning movement 1n order to direct the travel of the implement.

At its forward end the frame 20 carries tion engine, the crankshaft of which is connected 1n any manner known in the art with a differential gear upon the aXle 21 of the traction wheels 22; such gear and the connection between the same and the crankshaft of an engine being well known, it is thought that it is not necessary to go into a more detailed description of the same.

In the rear of the traction wheels 22 the longitudinal frame members 20, 20 are each provided with a depending bracket 35, having `a plurality of holes 36 therein, the holes in said t-wo brackets registering with each other so as to be adapted to be engaged by a transverse bar 37, which is held in position therein by cotter pins 38, 38. To this bar is attached byr meansA of two inclined Vframe members B9, 39 a Substantially tri- 'a motor 34, preferably an internal combus-y v members of the frame 2O of the implement. To the diagonally disposed portion 41 of the auxiliary fra1ne'40 are rigidly attached a plurality of substantially vertical downwardly projecting supporting members 42, 42, to the lower endsV of which are adjustably fastened by -means of clamps 43 the plow beams 43, 43.y These beams are arranged in pairs and extend toward the front of the implement. Each pair is fastened to4 a plate member 45, preferablyV by means of a bolt 44, passing through said pair and through one of the perforations 46 of the plate, which rests upon the bar 37. These plate members are vprovided at their forward ends with rollers 47, guided -in their upward and downward movement in vertically arranged channel-irons 48, which are either made integral with or attached to the brackets 35 hereinbefore' described. To the rear ends of the plow beams 43 are attached in a manner known in the art the turning plowsy 49, which may be ofany -suitable size and type, according to therequirements.

Tn the lower end of each supporting member 42 is rotatably'mounted a spindle 51. To this spindle is keyed or otherwise attached a colter comprising a disk 52, provided with radial recesses 53, in which are seated cutters or knives 54, adjustably held therein by set screws 55. The cutters 54 `are arranged in front of the turning plows and in the plane of the land-sides of the saine; Upon the spindle 51 of each colter is fixedly mounted a worin gear 56,meshing with a worm 57 upon a shaft 58, which latter is suitably journaled in the frame 40, and provided upon its upper end with a bevel gear 59, meshing with a simil-ar gear 60. The bevel gears 60 are keyed to a shaft 62, which is journaled in bearings `63, 63,v

carried by the frame 40. Rotation is imparted to the shaft 62 from `a countersha'ft G4, which is journaled in bearings 65, 65 upon the main frame of the implement.

- This countershaft is actuated from the main driving shaft 66, the latter being in turn actuated from the crankshaft of the internal combustion engine 34. The connection between the shafts `62 and 64 consists of sprocket wheels 67 andr 68, which are keyed to the shafts G2 and 64, respectively, and over which runs a chain 69. The, worm gears 56 and the worms 57 are inclosed by casings 50', which are secured to supporting rosalie eccentric 72, the strap 73 of which is provided with a yoke-like extension 74, having substantially vertical slots 75, 75, in which are seated bolts 47 6, 76, which are fastened to the plow beams 43. Tn the upper portion of the strap 73 is provided a recess, in which is seated'a roller 77, adapted to engage a inotch 78 in the peripheral portion of the eccentric 72. This notch is formed' in that portion of the eccentric which forms the most distant ortion thereof with relation to the shaft rangement will be hereinafter described.

It is obvious that in rotating the .shaft 70, the eccentric 72 will act upon the' strap 73 'and raise thereby the" auxiliary frame around the points thereof which are placed upon the bar 37, the auxiliary frame being swung around its pivots. The shaft is actuated from the countershaft 64 by providing the latter with a sprocket wheel 79, engaging Va chain 80, which runs over a sprocket wheel 81, the latter being-mounted upon a sleeve 82 drawn over aportion of the shaft 70. This sleeve carries a disk .83, provided with two recesses 84, 84 in 0. The purpose of this arver 90, fulcrumed at 91 to some stationary y part ofthe main frame 20, and connected by means of an actuating rod 92 `with a treadle `93, which is located wit-hin the reach of the operator occupying the seat 26. In placing his foot upon the treadle 93, the operator can act-nate the bellcrank lever 90, and swingthe same out of the path of the pinsv85 so that one of the same, when reaching its lowermost position, is

adaptedto enter, under the tension of the spring 88, one of the recesses 84 in the disk 83. Since the disk 83 rotates continuously, rotation will be im'parted to the shaft 70 whens one of the pins 85 enters one of the recesses 84, until asemi-circular stationary strip 94 in the path of the pin 85 disengages the latter from its recess 84. Each pin is provided with a screw-like groove 95, which is engaged by the strip 94 before said pin reaches its uppermost position. As soon as it is engaged, the pin will be moved against the action of the spring [88 toward the disk 87 and thereby disengaged from the disk 83, more particularly it will be disengaged when said pin reaches itsuppermost position. At the same time, however, the other pin reaches itslowermost position,

-tends substantially through half of the periphery of the disk 87, and is kept in engagement with a pin until the latter reaches the bellcrank leverV 90, when the said pin is disengaged from said strip and engaged with the bellcrank lever.

The operation ofthe implement is as folf, lows: When the machine has reached a fieldl brackets 35, and, if necessary, the bolts 44 in one or the other set of perforations in the plate members 45 to adjust properly the plow beams 43. The treadle 93 is then actuated to lower the plows to their desired positions. When the plow beams are in.

their uppermost positions, oneof the pins 85 is kept by the bell-crank lever 90 in one of the recesses 86 in the disk 87, and the other pin 85 isinengagementwith'the strip 94, and disengaged from its corresponding recess 84. As soon as the treadle is actu` ated, the bellcrank lever 90 is swung away from the disk 87, when, under the action of the spring 188, the lower pin 85 will enter one of the recesses 84 as soon as this recess registers' with the pin. When engaged with said recess, rotation will be imparted to the shaft 70, whereby the roller 77 of the strap 73 of the eccentric will be unseated from the notch 78 in the eccentric 7 2, and the `frame 40 with the parts carried thereby lowered. As soon as the pin reaches the strip 94, it will be gradually unseated from its recess, and the other` pin will be brought opposite to thebellcrank lever 90, which had been in the meantime returned toits normal operative position. ln starting now the movement of the `implement, the colters, to which rotation is imparted in t-he manner,` hereinbefore described, will cut the soil preparatory to its being turnedby the mold-boards of the plow, more particularly the Icolters will perform an initial cutting to facilitate the cutting action of the share of the plow. They will cut the soil eftectivelyas positive rotating movement is imparted to the same. The knives or cutters 54 may be adjusted by means `of the set screws 55 to a desired I depth, and may be reversed if one of the cutting edges of the same becomesdull.V lt

will be observed that the steering wheel 23 `f is a furrow wheel, while that traction wheel which is located atthe right-hand side of the driveris a land-wheel.

The auxiliary frame 40 with the parts thereon may be lifted whenever the plowing operation is to be stopped, or when an obe struction in the path of the plow is found. The roller 77, in engaging the Anotch 78 in t-he eccentric 72, will stop the said eccentric notwithstanding the momentum possessed thereby.

Itis obvious that the position of each pair of turning plows can be adjusted independently of the other pair.

Since the plow beams 43 are adjustably fastened by means of the clamps 43 to the supporting members 42, it will be easily seen that the positions of the colters relative to the turningplows maybe varied, at will, in order to change the relative depth of cut of said colters.

What I claim is In a power driven implement of the class described, the combination with a main frame, of an auxiliary frame pivotally secured thereto, a pluralit of plow beams mounted upon -said auxiliary frame, plows carried by said beams, the positions of the pivots upon said mainframe being adapt-V ed to be varied so as to predetrmine the depth ofthe cut of said plows, colters rotatably mounted upon said beams in front of said plows, means for raising or lowering said plow beams together withthe lparts attachedsthereto, and 'means for imparting rotation tosaid colters, substantially as and for the purpose specified.
